What type of screws would work best for hanging a projector from the ceiling?

I'm assuming your projector isn't terribly heavy, so... 2 1/2" gold construction screws should work fine to hold the board to the joists. I also like to use decking screws because of their strength ...

My AV rack (metal) is close to the grounding rod & my receiver/projector frequently get fried

Grounding is almost never the enemy. The ground rods being nearby has no bearing on the equipment. Electricity doesn't know anything about paths it can't take. It can't go even 1 foot through ...

Can a multi-meter be used to test home theater receiver speaker output?
